Yeah, we need "Stories from the Shady Dragon" - do several classic D&D (Mystara) adventures. This could be something like B1 - Into the Unknown, B3 - Palace of the Silver Princess, B10 - Night's Dark Terror, X4 - Master of the Desert Nomads, X5 - Temple of Death, X10 - Red Arrow, Black Shield, and ending with CM1 - Test of the Warlords. While mostly an anthology, there is a theme being land/army management - the party clears out and gets access to a underground stronghold, removes a curse from a kingdom (thus gaining its favor, possibly titles), fights the kingdom's various enemies and builds an army and eventually establish their own realm. Not only do we get some old material updated, it's a place where mass combat and realm rules can be fleshed out.
And there's plenty of inns/taverns that could be used for further anthologies if we want to use the inn/tavern theme.
Comeback Inn (Mystara/Blackmoor)
Green Griffon Tavern/Inn (Greyhawk)
Inn of the Last Home (Dragonlance)
World Serpent Inn (Planescape)
Inn of the Welcome Wench (Greyhawk)
